R语言绘制数据可视化Dumbbell plot哑铃图

data <- read.csv(“your file path”, header = T, check.names=F)
#注释：header=T表示数据中的第一行是列名，如果没有列名就用header=F
#注释：R读取数据的时候，默认会把列名里的空格变成 "."，check.names=F就不会变了

library(ggplot2) 
library(reshape2)              
# 注释：package使用之前需要调用

data_melt <- melt(data,id.vars = "Gene")
# 注释：将原始的宽数据变成长数据，方便画图
p <- ggplot(data_melt,aes(x = value, y = Gene)) +  
       geom_line(aes(group = Gene)) +
       geom_point(aes(fill = variable), size = 3)
